Training‐Free Regulation of Grasping by Intracortical Tactile Feedback Designed via S1‐M1 Communication

Advanced Science
Tactile feedback is essential for grip force control when operating a neuroprosthesis. Due to limited knowledge of cortical sensorimotor coordination, artificial feedback is mostly counterintuitive, requiring training to be associated with grasping ...

Configuring intracortical microelectrode arrays and stimulus parameters to minimize neuron loss during prolonged intracortical electrical stimulation

Brain Stimulation, 2021
Background: Previous studies have shown that neurons of the cerebral cortex can be injured by implantation of, and stimulation with, implanted microelectrodes.

Equalization for intracortical microstimulation artifact reduction [PDF]

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
We present a method for decreasing the duration of artifacts present during intra-cortical microstimulation (ICMS) recordings by using techniques developed for digital communications. We replace the traditional monophasic or biphasic current stimulation pulse with a patterned pulse stream produced by a Zero Forcing Equalizer (ZFE) filter after ...

Phase-Specific Microstimulation Differentially Modulates Beta Oscillations and Affects Behavior

Cell Reports, 2020
Summary: It is widely accepted that Beta-band oscillations play a role in sensorimotor behavior. To further explore this role, we developed a hybrid platform to combine neural operant conditioning and phase-specific intracortical microstimulation (ICMS).

The impact of closed-loop intracortical stimulation on neural activity in brain-injured, anesthetized animals

Bioelectronic Medicine, 2022
Background Acquired brain injuries, such as stroke, are a major cause of long-term disability worldwide. Intracortical microstimulation (ICMS) can be used successfully to assist in guiding appropriate connections to restore lost sensorimotor integration.

Forelimb movements evoked by optogenetic stimulation of the macaque motor cortex

Nature Communications, 2020
Non-human primates are useful models for understanding the human brain but application of optogenetics to non-human primates is challenging. The authors used optogenetic intracortical microstimulation in the primary motor cortex of macaques to elicit ...

Muscle synergies evoked by microstimulation are preferentially encoded during behavior

Frontiers in Computational Neuroscience, 2014
Electrical microstimulation studies provide some of the most direct evidence for the neural representation of muscle synergies. These synergies, i.e. coordinated activations of groups of muscles, have been proposed as building blocks for the construction

Perceived timing of cutaneous vibration and intracortical microstimulation of human somatosensory cortex

Brain Stimulation, 2022
Background: Intracortical microstimulation (ICMS) of somatosensory cortex can partially restore the sense of touch. Though ICMS bypasses much of the neuraxis, prior studies have found that conscious detection of touch elicited by ICMS lags behind the ...

Stoney vs. Histed: Quantifying the Spatial Effects of Intracortical Microstimulation

bioRxiv, 2021
Background Intracortical microstimulation (ICMS) is used to map neural circuits and restore lost sensory modalities such as vision, hearing, and somatosensation.
